Ever wonder how power washing crews get enough water to clean entire buildings, driveways, or parking garages? It’s a good question — and the answer depends on the job. So, where do power washing companies get their water? Most commonly, it comes from the client’s on-site water supply — but that’s not the only option.
Common Water Sources
- Customer’s Outdoor Spigot: This is the most typical source, especially for residential jobs. Crews hook up to your hose bib and use your water, often with a buffer tank for consistent flow.
- Onboard Water Tanks: Many professional power washing rigs include large water tanks. These are filled beforehand and used when on-site water isn’t available — a must for parking lots, construction sites, or rural properties.
- Hydrant Access (With Permits): For large commercial jobs, companies may coordinate with the local municipality to access water from fire hydrants. This requires proper permitting and metering.
Factors That Influence Water Source
- Job Size: Bigger jobs often require more water than a residential spigot can provide consistently.
- Location: Urban properties typically have accessible water; remote or new-construction sites may not.
- Type of Equipment: Hot water machines and high-volume sprayers need more pressure and flow, which may require tanked water.
Let the Pros Handle the Details
Reputable power washing companies will evaluate the site beforehand and plan accordingly — whether that means using your water, bringing their own, or securing a hydrant permit. You don’t need to worry about logistics — just ask how they plan to source water for your job, and they’ll handle the rest.
